Interesting. The 167.9 sub-audible tone suggests FBI. For links here in Chicago (no longer in use) the Feebs used 414.275, 419.55, 419.575, 408.225, 414.525, and 419.475. Don't remember if sub-audible tone was used.
Last link frequencies I heard they were using are 1714/1812 MHz and 1746/1842 MHz.
What kind of modulation are you hearing on the two frequencies you posted? Nothing, data, tones, voice?
